[3] Original facilities provided include a single manually operated 23 m (75 ft) diameter turntable with 42 radiating roads.

Twenty one of these roads were covered by a wooden framed roundhouse building clad in corrugated sheeting.

An office for the District Locomotive Engineer (referred to as the DLE) was constructed using concrete drop panels.

[6] A timber framed machine shop clad in corrugated iron served from one of the radial roads from No.

[8] A timber framed corrugated iron clad meal room for running staff capable of housing 140 men was also built near the workshop.

[9] Adjacent to the arrival road inspection pits and a timber framed stores building clad in corrugated iron was also provided.

Running underneath these pits at an angle was a sunken rail line where wagons were placed to collect the deposited ashes.

In 1925, these deashing pits had a steel and timber frame corrugated iron clad shed constructed over them.

[15] Improved facilities were provided for the employees at the depot in 1947 with a new meal, locker and shower room being built.

This building is of similar construction to the East shed section of the roundhouse completed in 1947 at Junee Locomotive Depot and has brick side and end walls with intermediate concrete columns and wooden roof trusses clad with corrugated sheeting.

A 1 tonne (1 long ton) radial hoist was fitted in the roof covering all 21 roads running above the drop pits.

A second 10 tonnes (7 long tons) capacity radial hoist was fitted over the drop pit roads.

Additional rooms for the maintenance of diesel loco components along with oil storage tanks were constructed at the rear of this new section.

[25] In 1966, a new diesel fuel storage facility was installed consisting of four 81,800 L (18,000 imp gal) tanks and pump house, additional fuelling points were provided on the new arrival roads.

[13][27] In March 1970, construction of a new Administrative and amenities building to the West of the original 1924 DLE's office was completed.

The locomotive then worked to Sydney on 4 March 1973 ending the steam allocation at Broadmeadow Loco Depot.

[15] Also in 1974 a steam cleaning shed was built on the straight transfer road between the two roundhouses adjacent to the original workshop building.

With the electrification of the Main Northern line from Wyong in June 1984, a siding was electrified adjacent to the depot for the servicing of electric locomotives.

1 shed, the turntable pit and surrounding radial roads were nominally raised by 470 mm to lessen the effect of groundwater.

[44] In early 2011, due to extensive vandal damage and being outside of the main heritage area the original 1924 concrete drop panel barracks was demolished.

In February 2013, a Hunter Division of Transport Heritage NSW was formed by local members of THNSW with the purpose of looking after the site & items stored there.

On 30 November 2018, Transport for New South Wales announced the creation of a new heritage hub at the former Chullora Railway Workshops site.

[3] Other equipment associated with the locomotive depot includes a 105-foot diameter electrically powered turntable and a number of small workshop and administrative buildings.

[3] Along the northern elevation is a group of tall cypress trees, possibly originally planted as a hedge.

Located east of and adjacent to Turntable # 2, is a metal framed structure, clad in corrugated iron, comprising two bays for refuelling.

One structure is long and thing in plan, open at both ends with high level mezzanines and a central pit for cleaning of rolling stock.

[3] South west of Turntable # 2 is a row of Canary Island date palms, following the line of the tracks.

The Chargemen's office, boilerhouse for the steam cleaning station and the machine shop were in the area now occupied by the Endeavour Workshop and little evidence of these is likely to survive.

Although a number of elements of the depot have been removed, the site is still able to demonstrate its significance through the grouping of the turntables, 1951-52 roundhouse, in and out roads and District Engineer's office.

[3] Broadmeadow Railway Locomotive Depot was listed on the New South Wales State Heritage Register on 2 April 1999, based on satisfying the criteria of historical significance and of rarity, being one of the few surviving examples of such a facility out of over a hundred built.
